Herbicides such as paraquat (PQ) are frequently utilized particularly in developing nations. The present research concentrated on the pulmonary lesions triggered by PQ and the beneficial effect of the angiotensin receptor neprilysin inhibitor (ARNI), sacubitril/valsartan, against such pulmonary damage. Five groups of rats were established: control, ARNI, PQ (10 mg/kg), ARNI 68 + PQ, and ARNI 34 + PQ.

In this work, we use experimental and theoretical techniques to study the origin of the boosted hydrogen evolution reaction (HER) catalytic activity of two pyridyl-pyrrolidine functionalized C fullerenes. Notably, the mono-(pyridyl-pyrrolidine) penta-adduct of C has exhibited a remarkable HER catalytic activity as a metal-free catalyst, delivering an overpotential () of 75 mV RHE and a very low onset potential of -45 mV RHE. This work addresses fundamental questions about how functionalization on C changes the electron density on fullerene cages for high-performance HER electrocatalysis.

Background: Machine perfusion (MP), including hypothermic oxygenated machine perfusion (HOPE), dual HOPE, normothermic machine perfusion (NMP), NMP ischemia-free liver transplantation (NMP-ILT), and controlled oxygenated rewarming (COR), is increasingly being investigated to improve liver graft quality from extended criteria donors and donors after circulatory death and expand the donor pool. This network meta-analysis investigates the comparative efficacy and safety of various liver MP strategies versus traditional static cold storage (SCS).

Methods: We searched PubMed, Scopus, Web of Science, and Cochrane Controlled Register of Trials for randomized controlled trials (RCTs) comparing liver transplantation (LT) outcomes between SCS and MP techniques.

Objectives: Diabetes mellitus is a chronic disease that has become more prevalent worldwide because of lifestyle changes. It leads to serious complications, including increased atherosclerosis, protein glycosylation, endothelial dysfunction, and vascular denervation. These complications impair neovascularization and wound healing, resulting in delayed recovery from injuries and an elevated risk of infections.

Department of Medical Rehabilitation Science, Faculty of Applied Medical Sciences, Umm Al-Qura University-Makkah-Saudi Arabia; Cairo University, Cairo, Egypt.

Introduction: Dual tasking (DT) requires individuals to carry out two actions simultaneously, comparable to how the brain can perform a cognitive function while the body is in motion, which eventually enhances human balance. This paper aims to examine and compare the impact of DT on the risk of falling (ROF) among Saudi female students.

Methods: A cross-sectional design was used.

Background: Epicardial fat tissue (EFT) is an active organ that can affect cardiac function and structure through endocrine, paracrine, and proinflammatory mechanisms. We hypothesized that greater thickness of EFT may harm the recovery of left ventricular (LV) systolic function in patients with severe aortic stenosis (AS) and reduced LV ejection fraction (EF ≤ 50 %) undergoing transcatheter aortic valve implantation (TAVI).

Methods: A sixty six patients with severe AS and 20 % ≥ LVEF ≤ 50 % who underwent TAVI were included.
